BALL APPLICATOR ATTACHMENT FOR BOTTLES Filed March 11, 1958 Fig. 2

INVENTOR: w film 0f b iad C M1194 United States BALL APPLICATOR ATTACHMENT FOR BOTTLES Alex Kundert, Ruschlikon, Switzerland, assignor to Florilham S.A., Monte Carlo, Monaco, a corporation of Monaco My present invention relates to a bottle-like closable container comprising means for spreading or applying the liquid in the container to a surface. Said container may contain perfume, tinctures, spirits of ammonia for treating insect stings, or other liquids which have to be applied in measured quantities to a surface, mostly to a defined skin portion. When the cap is screwed home on the bottle neck threads, the bottle is hermetically closed so that the liquid cannot evaporate.

Two forms of the invention are shown, by way of; example, in the drawing in vertical section. g

Fig. 1 is a sectional view of a closable container ac-- cording to the present invention;

Fig 2 is a sectional view of a closable container ac cording to the present invention in which somfeaturfes shownin' Fig. l are modified.

'The" container 1 shown in Fig. 1 comprises a ne'ck2 with'a cylindricalthroat 3 and external threads 4. "On to'the latter is screwed an elongated hollow cap 5 having a'rounde'd tip with an axial bore 6 of which the exterior opening is constricted and forms a seat 7 for a ground and polished ball 8 made of stainless steel, glass or the like. The diameter of ball 8 is approximately .15 millimeter smaller than that of bore 6, and ball 8 slightly protrudes from the opening of seat 7. 'In the cylindrical bore 3 ofneck2 is movably guided, in a snug fit, one end-portion of a' tube 9 made of plastic possessing a oer-f ta'in' degreeof elasticity, of which the other endiporti on' is also guided in a snug fit in bore 6 of cap 5 and forms a scatter ball 8. Tube 9 in its intermediate portion 5 forms an abutment forthe upper rim of collar 10, i.e. the rim adjacent the tip of cap 5. Between collar 10 of tube 9 and the; rim of, neck 2 of container 11 is inserted incap 5.21. ap red ring 12 made o f plastic oi. which theilowerrim portionbears on a" sho'uIderJS p oilided, iii

cap? and which 'locate sthe collar 10"and thustube 9 in cap 5. In the drawing, the width of shoulder 13 is exaggerated for the sake of clarity, and in reality said shoulder is of only such width that ring 12 thanks to its elasticity may be pushed into cap 5 and then is held therein by shoulder 13.

After container 1 has been filled with liquid, cap 5 is screwed on to the threads 4 of neck 2, the lower end portion of tube 9 which is held in cap 5 being pushed like a stopper into opening 3 of neck '2 and being a tight fit therein. In the position of non-use, as shown in the drawing, cap 5 is screwed home on the threads 4 of neck2 and ball 8 thereby. is clamped in bore' 6 between the exterior end of tube 9 and seat 7 and closes the mouth of tube 9 tightly. Container 1 thus is hermetically closed. In this'position of non-use, there is a a completerevolution. As, in such operation tube 9 is held in bore 3 of neck 2, bal118 is released from its clamped position between seat 7 and the'exterior end of M 2,974,351 V Patented Mar. 14, 1.96. 1

.. tube 9 and can turn whereby the mouth of tube 9 is set free. When container 1 with cap 5 is. turned upside down, liquid seeping out of tube 9 may form a'liquid film on ball 8 by virtue of the fact that the diameter of 5 the latter is slightly less than that of bore 6 in cap :5, which liquid may be applied to a surface. Since tube 9 is a relatively tight fit in bore 6 of cap 5, no liquid canflow into the hollow space of cap 5 when turning 15 bore 3 of neck 2 is slightly moved outwardly but is'again pushed into bore 3 when subsequently screwing .home

cap 5. r

In. the second form of the invention (Fig. 2) 21desi-g-l In this. case also, neck 22. has a cylindrical opening 23 and.

nates the container and 22 the neckthereof.

external threads 24 on to which is screwed a cap 25. In the tip of cap 25, which has the same external appear-'. ance as in the firstexarnple, is provided a bore. 26 of which the external mouth is constricted and forms. a

seat 27. for a ball 28 of a diameter slightly less than that .of bore 26. In the latter is sealingly guided the ex-.

terior end. of a'tube 29 of .which the interiorlend is' v sealingly guided inthe, opening 23 of neck 22. Here also, tube 29 is madeofan' elastic. plasticandcomprises 30 in its intermediate, portiona collar 30, and a shoulder 31 provided in cap 25 forms an abutment for the'collar face 30 adjacentthe tip of cap 25. A threadedtubular sleeve 32 is screwed intofthe'threads'of cap '25adjacentl thelowerend of shoulder 30, whichlsleevelocatesfthe' 35 shoulder 30 and thus ,tube 29 in cap, 25.
